摘　　要： [目的]探讨石香薷主要成分麝香草酚对植物病原菌的影响。[方法]采用管碟法研究麝香草酚对13种致病微生物的抑制作用。[结果]麝香草酚对13种受试菌均有不同程度的抑制作用,其中对水稻恶苗病菌、黄瓜枯萎病菌、黄瓜炭疽病菌、油菜菌核病菌4种植物病害真菌的抑制效果极显著,抑菌效果与麝香草酚浓度呈正相关,对这4种真菌的最低抑菌浓度(MIC)分别为0.125、0.063、0.063、0.250 mg/mL,最低杀菌浓度(MBC)分别为0.125、0.125、0.063、3.000 mg/mL。[结论]试验结果可为麝香草酚的进一步研究提供理论依据。 [ Objective] The aim was to explore effects of thymol on the plant pathogenic microorganism. [ Method] We studied the inhibitory activity of thymol on 13 kinds of pathogenic microorganism by cup-plate method. [ Result] The thymol couldeffectively inhibit the growth of tested kinds of bacteria, and could inhibit significantly four kinds of plant disease fungus,which were Fusarium moniliforme Sheldon,Fusarium oxysporum Schlecht,Colletorichum orbiculare and Sclerotinia sclerotiorum. The bacteriostatic effect was positive correlation to the concentration of thymol. The minimum inhibitory concentration（MIC） of thymol on four kinds of plant disease fungus were 0. 125,0. 063,0. 063 and 0. 250 mg/mL,and the minimum bactericidal concentration （MBC） were 0. 125,0. 125,0.063 and 3. 000 mg/mL,respectively. [ Conclusion ] The results provide reference for further research on thymol.
